Health and Human Services Secretary Tom Price says he is reimbursing U.S. taxpayers for his official travel on private charter planes.

In a statement released on Thursday, he said, "Today, I will write a personal check to the US Treasury for the expenses of my travel on private charter planes. The taxpayers won't pay a dime for my seat on those planes."

The expense for his seat on those planes comes out to $51,887.31, according to an HHS spokesperson.

Arizona Sen. John McCain has been diagnosed with brain cancer, the Mayo Clinic Hospital in Phoenix says. McCain, 80, underwent surgery for a blood clot on July 14.

The hospital says testing revealed that a tumor "known as a glioblastoma was associated with the blood clot."

"The Senator and his family are reviewing further treatment options with his Mayo Clinic care team. Treatment options may include a combination of chemotherapy and radiation," the hospital statement said.

President Trump said he would invite Russian President Vladimir Putin to the White House "at the right time" when asked by a reporter on Air Force One Wednesday night.

"I don't think this is the right time, but the answer is yes I would," he said, according to a pool report released on Thursday. "Look, it's very easy for me to say absolutely, I won't. That's the easy thing for me to do, but that's the stupid thing to do."

President Trump dismissed a potential obstruction of justice investigation into his conduct, calling allegations of collusion between him, his campaign or people associated with him and Russia a "phony story."
